Color Converter for Nokia Symbian Anna / Belle

I’ve developed a small Qt Quick application called ColorConv that can convert RGB color to HEX color used in HTML pages (e.g. 255,255,255 -> #FFFFFF) and vice versa mainly to play with Qt Creator QML and test Nokia Ovi Store application submission process. You can enter the Red, Green, Blue values manually by typing with the default numerical keypad in Symbian or use the slider to select the value. Alternatively you can enter the hexadecimal code to get the RGB value. If you are interested, you can download it in Ovi Store and in case you have some requests please comment on the support page. Nokia Ovi Store Submission Process Nokia submission process is almost free (1 Euro) and it took about 2 weeks to get my application published. I basically followed the instructions given on submit Qt applications to the Ovi Store PDF. The first thing you have to […]

Qt Labs Releases Qt 4.8.0

Qt Labs has just announced the release of Qt 4.8.0 featuring Qt Platform Abstraction, threaded OpenGL support, multithreaded HTTP and optimized file system access. Here are some of the new key features  in Qt 4.8.0: Qt Platform Abstraction (QPA) QPA restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. Previously called Lighthouse. Threaded OpenGL supportEnables developers to render OpenGL from more than one thread concurrently. See Threaded OpenGL in 4.8 for more details. Multithreaded HTTP HTTP requests are now handled in a separate thread by default. This should make application guis smoother, as networking will no longer use the main event loop. Optimized file system access The file system stack received some heavy lifting under the hood. The result is better I/O performance, achieved by reducing the number of system calls performed for I/O and by better use of cached data, when available. […]

Nokia Developer Day 2: Qt QML Workshop – Chiang Mai

I’ve just attended Nokia Developer Day  on 6-7 December 2011 in Chiang Mai. I’ve already written a summary about the first day dealing with Series 40 Java and Web Apps Workshop. The second day was focused on Qt/QML (Qt Meta-Language) software development for Nokia’s Symbian phones. Nokia will phase out Symbian operating system in 2016, but they’ll still support it until that time. Nokia will also port  Qt to lower end phones (e.g. Series 40) on a new operating system based on Linux called Meltemi. Overall Business Direction & Strategy The first 45-minutes for was presentation given by Grant Aaron McBeath, Managing Director, Nokia Thailand and Emerging Asia, about Nokia business direction: focus on Windows Phone for smartphones, Java/Web Apps for feature phones and future disruption. He also showed the progress of Nokia Ovi Store with 10 million downloads a day and 177 publishers with more than 1 million downloads. […]

Nokia Developer Day 1 Summary – Chiang Mai

I’ve just attended the first day of Nokia Developer Day (6-7 December 2011). The focus was on software development for Nokia’s feature phones with Java or Web Apps (HTML/CSS/Javascript) and most of the time was spent on workshops to get started for developing for Nokia feature phones such as the S40 series. Introduction to Ecosystem Business Updates During the first 15 minutes, an “Introduction to Ecosystem Business Updates” was given by Jirapat Janjerdask, Head of the Ecosystem Developer Experience at Nokia Thailand. He gave an overview of the ecosystem for features phones including the brand, developer & publisher, mobile brand, mobile operator and consumer. One interesting statistics was that there are 10 millions app downloads every single day. He also talked about the new Nokia Asha 300 and 303 features phones available for 3000 to 4000 Thai Baht (100 to 130 USD)  that are capable of running applications that usually […]

The Linux NFC Subsystem – ELCE 2011

Lauro Ramos Venancio, Instituto Nokia de Tecnologia and Samuel Ortiz, Intel give a presentation about the NFC subsystem in Linux at Embedded Linux Conference Europe 2011. Abstract: NFC (Near Field Communication) is a wireless protocol mostly designed for fast information reading and writing from nearby devices and tags. It also allows NFC devices to establish a transport layer link and exchange larger chunks of data. While Android ships with its own multi platform NFC stack writing HCI frames to a raw character device and supporting one single device, Linux is currently missing any kind of generic and clean NFC support, from both kernel and user space (cnxsoft: Since end of last month, this is not the case as Linux 3.1 supports NFC). Therefore, a new socket family for NFC, along with a kernel netlink API for high level NFC commands passing is being developed. An NFC user space daemon abstracts […]
